Product Description

The LM46000PWPT is a SIMPLE SWITCHER® easy-to-use synchronous step-down DC-to-DC Converter capable of driving up to 500mA of load current from an input voltage range of 3.5 to 60V. The LM46000 provides exceptional efficiency, output accuracy and dropout voltage in a very small solution size. Peak current mode control is employed to achieve simple control loop compensation and cycle-by-cycle current limiting. Optional features such as programmable switching frequency, synchronization, power-good flag, precision enable, internal soft-start, extendable soft-start and tracking provide a flexible and easy to use platform for a wide range of applications. Discontinuous conduction and automatic frequency modulation at light loads improve light load efficiency. The family requires few external components and pin arrangement allows simple, optimum PCB layout. Protection features include thermal shutdown, VCC undervoltage lockout and cycle-by-cycle current limit.
High efficiency at light load (DCM and PFM)
Integrated synchronous rectification
Frequency synchronization to external clock
Internal compensation
Stable with almost any combination of ceramic, polymer, tantalum and aluminium capacitors
Power-good flag
Soft-start into pre-biased load
Extendable soft-start time by external capacitor
Output voltage tracking capability
Precision enable to program system UVLO
Output short-circuit protection with hiccup mode
24µA Quiescent current in regulation
4.1ms Internal soft-start
Green product and no Sb/Br
